I have a question regarding the best speaker placement for our venue. Unfortunately, the venue is about 2:1 width to length. It's quite small, about 30' long and 60' wide. The stage comes off the back wall about 9'6" and is approximately 25' wide. We have 4 speakers suspended at the front of the stage, fanned out in a slight arc around the front of the stage. Looking at the stage from the center of the room, you'd see a speaker slightly to your right and slightly to your left, each slightly fanned out from center, and one at each corner of the stage fanned more drastically towards the corners of the room.
This causes a noticeable amount of dropout between speakers due to how close they are to the audience, with the distance from the speakers to the back wall being only about 20'.
One professional suggestion I received was to ditch two speakers, and simply have one at either front corner of the stage pointed at the opposite corner so that their overlap converged in the middle of the room at a 45 degree angle, instead of having slight overlap from one to the next at a slight angle.
Any suggestions to support this idea, or give new ideas for where to put the speakers?
